Plain English Summary

3/10 complexity

Applies to all Consolidated Aeronautics Colonial and LA‑4 series aeroplanes: this AD mandates inspection of the rudder bellcrank (per Consolidated Aeronautics SL L‑50) within 100 hours TIS after 30 Apr 1974, thereafter at intervals not exceeding one year, and after any event imposing abnormal rudder‑pedal loads. Owners/operators must arrange and pay for inspections and any repairs. It matters because it creates a recurring safety check and predictable maintenance cost, and requires access to the referenced inspection procedure.
